December 2015Comparing Asset Pricing Models
with Jay Shanken: w21771
A Bayesian asset-pricing test is derived that is easily computed in closed-form from the standard F-statistic. Given a set of candidate traded factors, we develop a related test procedure that permits an analysis of model comparison, i.e., the computation of model probabilities for the collection of all possible pricing models that are based on subsets of the given factors. We find that the recent models of Hou, Xue and Zhang (2015a,b) and Fama and French (2015a,b) are both dominated by five and six-factor models that include a momentum factor, along with value and profitability factors that are updated monthly.

November 2015Which Alpha?
with Jay Shanken: w21698
A common approach to comparing asset pricing models with traded factors involves a competition between models in pricing test-asset returns. We find that such practice, while seemingly reasonable, cannot be relied on to determine which is the superior model for several widely accepted criteria including statistical likelihood, Sharpe ratios and a modified HJ distance. All that matters for model comparison is the extent to which each model is able to price the factors in the other model. Given this information, test assets are actually irrelevant, whether the models are nested or non-nested.
